While most rats gain weight when placed on a high-fat diet (HFD), some strains resist HFD-induced weight gain. To maintain weight, obesity-resistant (OR) rats must either eat less than obesity-prone (OP) rats or increase total energy expenditure (TEE). To determine if changes in TEE predispose to or protect from weight gain, energy expenditure, energy intake, and weight gain were measured in ma...

Introduction: Opposite observations about the discrepancy in the pain perception between male and female has been reported. In this regard, pain thresholds among male and female rats in different phases of oestrous cycle were evaluated via tail immersion test. In addition, efficiency of alcoholic extract of datura stramonium as an analgesic plant in the modulation of acute pain threshold has be...

Traditional medicinal plants are widely used as immunomodulatory medicines that help improve health. A total of 50 for the treatment toxicity were screened their protective effects. globally and have rapidly grown in economic importance. Intrinsically active compounds well-known antioxidant, anti-tumor, anti-viral, anti-inflammatory activities. The study was conducted to investigate effects eth...

Alteration in capacity and function of proximal distal convoluted tubules kidney exposed by Molybdenum trioxide nanoparticles female rats (Stereological technique)

background: several cells of immune system such as regulatory t cells and macrophages secrete transforming growth factor-β (tgf-β) in response to different stimuli. this cytokine has inhibitory effect on immune system and diminished production of this cytokine is associated with autoimmune disorders. objective: the aim of this study was to evaluate the influence of opium addiction on serum leve...

objective(s): several researchers have reported the relationship between infertility in male and varicocele for so many years but the implication of varicocele in female patients is remains elusive. here, we aim to examine the effects of unilateral varicose ovarian vein on antioxidant capacity and oocyte quality of rat ovary after the experimental creation of varicocele in female rats. material...

Female rats treated with deoxycorticosterone acetate (DOCA) and salt do not get as hypertensive as male DOCA-salt treated rats. The adrenal gland contributes to the development and maintenance of DOCA-salt hypertension in male rats. However, little is known about adrenal medullary function in DOCA-salt hypertensive female rats. This study tested the hypothesis that bilateral removal of the adre...

–The present study investigated the effects of 21 days of chronic restraint stress on neural and endocrine parameters in male and female rats. Consistent with previous results, repeated restraint stress induced apical dendritic atrophy (a decrease in the number of apical branch points and dendritic length) of the CA3c pyramidal neurons in male rats. In contrast, female rats did not show signifi...

In resistance arteries, a chronic increase in blood flow induces hypertrophic outward remodeling. This flow-mediated remodeling (FMR) is absent in male rats aged 10 mo and more. As FMR depends on estrogens in 3-mo-old female rats, we hypothesized that it might be preserved in 12-mo-old female rats. Blood flow was increased in vivo in mesenteric resistance arteries after ligation of the side art...

Cotton rats, roof rats, and rice rats collectively inflict significant damage to sugarcane crops in the Everglades Agricultural Area; however, the relative damage inflicted by each species is unknown. A feeding trial experiment showed that some differences existed in the grams of sugarcane consumed per gram of body mass among species (male cotton rats: 0.39 ± 0.03g; female cotton rats: 0.34 ± 0...
